Portfolio overview
Sungrow Power Supply Co., Ltd. has been granted 170 US utility patents between 2016 and 2025, placing Sungrow Power Supply Co., Ltd. at rank #2,303 across all assignees tracked by PlainPatent. This portfolio spans 43 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.2 claims per patent with primary concentration in Y02E (REDUCTION OF GREENHOUSE GAS [GHG] EMISSIONS, RELATED TO ENERGY GENERATION, TRANSMISSION OR DISTRIBUTION). As a Foreign Corporation, Sungrow Power Supply Co., Ltd. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 56.1/100 blends portfolio volume, filing velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.
Filing cadence tells the strategic story. Between 2020 and 2025 the company received 132 grants, compared with 38 in the 2015–2019 window — a +247% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. The Foreign Corporation classification further shapes interpretation, since corporate, government, and individual filers pursue patents for materially different reasons.
Claim depth and technology breadth together indicate competitive posture. Sungrow Power Supply Co., Ltd.'s 12.2 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 43 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Sungrow Power Supply Co., Ltd. against peers pursuing similar technology classes.
